Variables
constexpr std::array< std::uint8_t, 4 >	sparrow_ipc::continuation = {0xFF, 0xFF, 0xFF, 0xFF}
	Continuation value defined in the Arrow IPC specification: https://arrow.apache.org/docs/format/Columnar.html#encapsulated-message-format.
constexpr std::array< std::uint8_t, 8 >	sparrow_ipc::end_of_stream = {0xFF, 0xFF, 0xFF, 0xFF, 0x00, 0x00, 0x00, 0x00}
	End-of-stream marker defined in the Arrow IPC specification: https://arrow.apache.org/docs/format/Columnar.html#ipc-streaming-format.
constexpr std::array< std::uint8_t, 6 >	sparrow_ipc::arrow_file_magic = {'A', 'R', 'R', 'O', 'W', '1'}
	Magic bytes for Arrow file format defined in the Arrow IPC specification: https://arrow.apache.org/docs/format/Columnar.html#ipc-file-format The magic string is "ARROW1" (6 bytes) followed by 2 padding bytes to reach 8-byte alignment.
constexpr std::size_t	sparrow_ipc::arrow_file_magic_size = arrow_file_magic.size()
constexpr std::array< std::uint8_t, 8 >	sparrow_ipc::arrow_file_header_magic = {'A', 'R', 'R', 'O', 'W', '1', 0x00, 0x00}
	Magic bytes with padding for file header (8 bytes total for alignment)
